Monitoring the Photothermal Reshaping of Individual Plasmonic Nanorods with Coherent Mechanical Oscillations
(2018-12-03)
Light absorption in gold nanoparticles leads to metal heating that induces photothermal reshaping because of atomic surface diffusion at temperatures well below the gold melting point. In this work, we perform time-resolved ...
Nanorod-based plasmonic substrates with predefined optical resonances
(2018)
To design and fabricate plasmonic substrates to be used in ultrasensitive chemical sensing or surfaceenhanced
spectroscopies, it is important to achieve control on the morphology, dimensions and
surface density of metallic ...
High resolution imaging using nanoparticle based probes
(2018)
New plasmonic probes, based on silica microspheres decorated with metal
nanoparticles (Figure 1), are built and used to confine and enhance the electric field
in their interaction with the sample, giving ultra-high optical ...
Síntesis de nanopartículas híbridas dieléctrico-metal y estudio de sus propiedades ópticas
(2018)
Se sintetizaron y estudiaron nanopartículas esféricas del tipo núcleo-cáscara de sílice y oro, con control de sus dimensiones. En una primera etapa se realizó la síntesis de esferas de SiO2 monodispersas de varios tamaños, ...
